Describe the bug

If I start Google Pay payment in production and then cancel it, the query parameters passed to my site contain checkout-provider: checkout.

Steps to Reproduce

1. Start Google Pay payment in production
2. Cancel payment
3. Check query parameters passed to callback url
4. Query parameters contain invalid value for checkout-provider

Expected behaviour

The checkout-provider query parameter should be google-pay.

Actual behaviour

The checkout-provider query parameter is checkout.
